PRM Modpack is a game modification within the S.T.A.L.K.E.R.: Lost Alpha universe.

- Some stalker


  • The PRM Modpack is primarily a weapon oriented Modpack that is released as an addon for v1.4005 and v1.4007.
  • The v1.4005 release was packaged with other coding (Gameplay DLC) as part of the "Extended Pack" that saw a number of iterations prior to the main game release of v1.4007.
  • When installed via the addon EP, v1.4005 is enhanced to v1.4006 with postfixes indicating that PRM and DLC are installed.


  • Of itself, the PRM Modpack operates within the principle game environment and makes no significant alterations to gameplay.
  • However, the modpack is closely integrated with the Gameplay DLC pack and that pack is a requirement for the PRM Modpack to function correctly.
  • In short, the two work synergistically in modifying v1.4005 to v1.4006.

Known Issues

Updating to newer versions of the weapon pack (other than the base version included as an option during installation of Director's Cut v1.4007) via the launcher breaks the in-game spawn menu accessible via Developer Mode (removes vast amounts of sub-menus and items in said menus, especially the "Toolkits" used for upgrading Technicians; often times the only reason the spawn menu is used by players).
